Answer:

By opting for the second option, Alice would save $ 15,740.00  in total mortgage cost

Step-by-step explanation:

In order to determine the better of the two options available, we need to determine the total cost under each option as follows:

Option 1:

cost of house=$625,000

loan amount=$625,000-(20%*$625,000)=$500,000

loan amount=monthly payment*(1-(1+r)^-n/r

monthly payment is the unknown

r=monthly interest rate=4%/12=0.33333333%

n=number of monthly payments in 30 years=30*12=360

500,000=monthly payment*(1-(1+0.33333333% )^-360/0.33333333%

500,000=monthly payment*(1-0.301795869 )/0.003333333

500,000=monthly payment*0.698204131 /0.003333333

monthly payment=500,000*0.003333333 /0.698204131

monthly payment=$ 2,387.08  

total monthly payments=$ 2,387.08*360=$859,348.80

Option 2:

upfront fee=$10,000

loan amount=monthly payment*(1-(1+r)^-n/r

monthly payment is the unknown

r=monthly interest rate=3.75%/12=0.3125%

n=number of monthly payments in 30 years=30*12=360

500,000=monthly payment*(1-(1+0.3125%  )^-360/0.3125%

500,000=monthly payment*(1-0.325222459  )/0.003125

500,000=monthly payment*0.674777541  /0.003125  

monthly payment=500,000*0.003125  /0.674777541=$2,315.58  

Total cost=total monthly payments+upfromt fee

total cost=($2,315.58 *360)+$10,000=$843,608.80  

savings by opting for the second option=$859,348.80-$843,608.80

Answer: Angle ABD is 39°

Step-by-step explanation:

Angle CBA is 90° (given by "box" on the corner of the right triangle)

Angle CBD is given as 51°

Subtract:

90° - 51° = 39°

Step one: (((x2)+x)+1)+((0-(2x23•x))+5)

Step two: Check for a perfect cube.  2.1    -2x24+x2+x+6  is not a perfect cube.

2.2      Factoring:  -2x24+x2+x+6

Thoughtfully split the expression at hand into groups, each group having two terms :

Group 1:  x+6

Group 2:  -2x24+x2

Pull out from each group separately :

Group 1:   (x+6) • (1)

Group 2:   (2x22-1) • (-x2)

The groups have no common factor and can not be added up to form a multiplication.

So the answer would be,  -2 (x24) + (x2) ++ 6.

Determine the number of selection

Since there is no condition attached, the number of selection is:

[tex]Selection = ^nC_r[/tex]

Substitute values for n and r

[tex]Selection = ^{12}C_3[/tex]

Apply combination formula

[tex]Selection = \frac{12!}{(12-3)!3!}[/tex]

[tex]Selection = \frac{12!}{9!3!}[/tex]

[tex]Selection = \frac{12*11*10*9!}{9!*3*2*1}[/tex]

[tex]Selection = \frac{12*11*10}{6}[/tex]

[tex]Selection = \frac{1320}{6}[/tex]

[tex]Selection = 220[/tex]

Hence, there are 220 possible ways

Answer:

$8.96

Step-by-step explanation:

To find the total amount, multiply the percentage of the tip (20%) as 0.20 with 7.47

(7.47×0.20=1.494)

Add $1.49 to $7.47

(1.49+7.47=8.96)

And there is your total amount with a 20% tip!

$8.96

Answer:

Step-by-step explanation:

((((((.5 mile = .25 hour<<<<<<<<<<<<<<<<<<<<<<<<<<

Multiply both sides by 4, because there are 4 quarters in 1 hour

(4)(.5) = (.25)(4)

2 miles =1 hr

Multiply both sides of the original equation by 3 to figure out how far in 3/4 of an hour

(3)(.5) = (3)(.25)

1.5 miles = 3/4 of an hour

now add the two answers together to figure out that the person walked 3.5 miles in 1 3/4 hours

***You also could have multiplied both sides of the original equation by 7, recognizing that that there are 7 quarters in 1.75 hours.

Answer:

Tyler's cell phone plan will cost 1,550 over the period of two years.

Step-by-step explanation:

$50 * 24 months = 1,200

1,200 + 350 = 1,550

The graph for the given condition is attached below.

An equation is a statement that two expressions, which include variables and/or numbers, are equal. In essence, equations are questions, and efforts to systematically find solutions to these questions have been the driving forces behind the creation of mathematics.

It is given that, Tyler's cell phone plan costs $350 to start, then there is a $50 charge each month.

Suppose the number of months is x and the total amount is y, The obtained equation for the given condition is,

y=350+50x

We have to graph the cost of Tyler's cell phone plan over a period of two years.

1 year = 12 month

2 year = 24 month

Suppose 24 as the place of x,

y=350+50x

y=350+50(24)

y=350+1200

y=1550

Thus, the graph for the given condition is attached below.

Answer:

Step-by-step explanation:

ΔSRQ and ΔVTU are similar Triangle.

Triangles are said to be congruent if, under a correspondence, two of a triangle's sides and the angle that connects them are equal to two of another triangle's sides and the angle that connects them.

Given two triangles, ΔRQS and ΔVUT such that,

RS = 16, QR= 64 and VT = 8, UT = 32

If two triangles have an equal number of corresponding sides and an equal number of corresponding angles, then they are comparable.

From the above condition since,

∠R = ∠T

and

[tex]\frac{QR}{SR} = \frac{UT}{VT} = \frac{4}{1}[/tex]

Thus,

ΔSRQ and ΔVTU are similar from the congruency  property of SAS.

The probability that more than one coin lands heads up is 0.9375.

In an experiment with two possible outcomes, the likelihood of exactly x successes on n repeated trials is known as the binomial probability.

The binomial probability is [tex]^nC_xp^xq^{n-x}[/tex].

Given, Four fair coins are flipped and the number of heads that land face up are counted.

Let, 'p' be the probability of getting a head and 'q' be the probability of getting a tail,

So, p = 1/2 and q= 1/2.

Therefore, The probability that more than one coin lands heads up is,

P(X ≥ 1) = P(X = 1) + P(X = 2) + P(X = 3) + P(X = 3).

P(X ≥ 1) = [tex]^4C_1p^1q^3 + ^4C_2p^2q^2 + ^4C_3p^3q^1 + ^4C_4p^4q^0[/tex].

P(X ≥ 1) = [tex]^4C_1(1/2)^1(1/2)^3 + ^4C_2(1/2)^2(1/2)^2 + ^4C_3(1/2)^3(1/2)^1 + ^4C_4(1/2)^4(1/2)^0[/tex].

P(X ≥ 1) = 4(0.5×0.125) + 6(0.25×0.25) + 4(0.125×0.5) + 1(0.0625).

P(X ≥ 1) = 0.25 + 0.375 + 0.25 + 0.0625.

P(X ≥ 1) = 0.9375.

So, The probability of getting one or more heads is 0.9375.

Step-by-step explanation:

Answer:

(a)

A single avocado costs $1

A single tomato costs $0.5

(b)

An avocado costs twice as much as a tomato

Step-by-step explanation:

Represent the tomatoes with T and the avocados with A.

So, we have:

[tex]4T + 8A = 10[/tex] --- (1)

[tex]6T + 14A = 17[/tex] --- (2)

Solving (a): The price of each

Multiply (1) by 1.5

[tex]1.5(4T + 8A = 10)[/tex]

[tex]6T + 12A = 15[/tex] --- (3)

Subtract (3) from (2)

[tex](6T + 14A = 17) - (6T + 12A = 15)[/tex]

[tex]6T - 6T + 14A - 12A = 17 - 15[/tex]

[tex]14A - 12A = 17 - 15[/tex]

[tex]2A = 2[/tex]

Divide both sides by 2

[tex]A = 1[/tex]

Substitute 1 for A in (1)

[tex]4T + 8A = 10[/tex]

[tex]4T + 8(1) = 10[/tex]

[tex]4T + 8 = 10[/tex]

Make 4T the subject

[tex]4T = 10 - 8[/tex]

[tex]4T = 2[/tex]

Divide both sides by 4

[tex]T = \frac{2}{4}[/tex]

[tex]T = 0.5[/tex]

Solving (b): Analysis

In (a), we have:

[tex]T = 0.5[/tex]

[tex]A = 1[/tex]

We can say that an avocado costs twice as much as a tomato
